Prefetch Size
The prefetch size (bytes) in the converted file is not accessible with WAAPI.
You can access the value in the SoundBankInfo files (json/xml), generated with the Soundbank files:
"IncludedMemoryFiles": [
{
"Id": "230377263",
"Language": "SFX",
"ShortName": "2_blocks.wav",
"Path": "SFX\\2_blocks_D79FB2B7.wem",
"PrefetchSize": "9664"
}
We also plan on adding WAAPI a topic you can register to be notified when SoundBanks are generated, containing the prefetch size:

Prefetch Lenght
The prefetch lenght is accessible directly as a property on the Sound objects, see here:

PreFetchLength: Prefetch length (ms)
To access the value, use ak.wwise.core.object.get on Sound objects, with "@PreFetchLength" in the return options:
